There are only 5-Ingredients in this slow cooker or pressure cooker steak fajitas recipe. This easy yet delicious low-carb, paleo, and whole30 dish is perfect any day of the week.

Yesterday was National Margarita Day and I completely missed out. I will not miss out on Taco Tuesday! Fajitas count right? I’m all about simplicity these days so there are only 5 ingredients in this recipe and they are: beef, bell pepper, onion, salsa, and fajita seasoning.

Salsa – My slow cooker salsa is a great option! Otherwise use 15 ounces of your favorite brand or even diced tomatoes. You can even use salsa verde.

Seasoning – I won’t preach because I used to use a packet, but in general I heavily encourage you to ditch the store-bought seasoning packets. Below is my go-to homemade fajita seasoning. You probably have all these spices in your pantry already. This makes about 2 1/2 tbsp which is equivalent to 1 packet of store-bought. I make a big batch and keep a mason jar full of it in my cupboard.

Normally when I make this slow cooker steak fajitas recipe I only use 1 bell pepper. This time though, I wanted more veggies so I used two – a combo of red and green. I like to give this a good stir before putting the lid on so the salsa and seasonings are distributed evenly.

Set it and forget it. You can substitute chicken or pork instead of beef if you like. Heck I have even made these fajitas using a large turkey breast. The concept stays the same, just swap out the protein.

For my whole30/paleo folks, if you choose to NOT make your own salsa and use store-bought instead, look for one that uses all-natural ingredients and definitely don’t use one with added sugar.

I was looking for ideas for the crockpot tonight and found your recipe on Pinterest 🙂 I am definitely making these tonight and debating on which kitchen gadget to use (I have a bit too many lol.) Probably my Ninja since it slows cooks and more. The Ninja multi cooker I have has the stove top feature and then I can drop it down to slow cook.

Have you tried to saute before slow cooking? I do that with beef stew and I am wondering if searing it will be a good idea or if I should dump it all in and go. I would love to try it in the Instant Pot one day too, but I won’t be home early enough for that tonight.

I used the sirloin for my fajitas. I doubled the recipe for a big birthday party. I cooked them for a little less time than required. I used a slotted spoon when serving. They were a hit – turned out great! Many compliments! Leftovers were amazing, also! I made your fajita seasoning, and loved it. I did add a little more to the recipe than called for because we love the flavors. Thank you so much for a great recipe!

This is SO delicious. I made it a couple of weeks ago and my husband and I both LOVED it. I had mine over Mexican rice and he had his in corn tortillas. Made great leftovers, too. I halved it and it turned out great. The extra juices from cooking were great to spoon over rice. I’m making it again tomorrow for Sunday dinner. Thanks so much for a great recipe!

This is one of our favorite recipes. We actually think it tastes a lot like the ropa vieja from one of our favorite Cuban restaurants so instead of serving it in a tortilla, we put it over rice or cauliflower rice and make Cuban black beans that we mix into it. I have one question though. I want to make it for my father who does not like spices. What would you recommend cutting in order to make it a little less spicy but yet still maintain the flavor?

Hello, is the picture of the fajita spice exactly as your recipe on the blog? I see large bits if yellow and green in it. Looked so appetizing I want to make sure it comes out the same, but nothing in ingredient list seemed to be a spice with large colorful bits.

Hello! Want to try this recipe with a big piece of flank steak that I have. Wondering if it would seal in more flavour and keep the meat more moist if I slow cook it as a whole and slice it after? Or do you not think that will work?

I followed the recipe to a tee and we loved it! We do mass crockpot meal preps so we bagged and froze most of it, minus the salsa. We thawed the bag overnight in the fridge then dumped in the crock, added the salsa, and cooked 8 hrs on low. We have 3 more for the month and can’t wait til the next time it comes around!

I froze it raw. You pretty much make the meal as instructed, then bag & freeze it. A day before you’re ready to eat, pop the bag in the refrigerator. It should thaw by the next day. Then you cook as instructed. Enjoy!

I bought a frozen bag of mixed red and green bell peppers and onion, and the pre-sliced beef and this worked well. Since there was going to be extra liquid from the frozen veggies, I used 2 packs of taco seasoning instead of the salsa and it was yummy!

This was absolutely delicious! I followed the recipe to a T minus red pepper flakes. I am attempting the Whole 30 diet, and this is the first dinner recipe I’ve made since I started it (today Lol). That seasoning mix is perfect and this was great just on a plate with guacamole on top. Luckily it’s versatile, so my husband was also very pleased, as he ate his typical fajita style with all of the toppings. So easy, so delicious and can change to go with almost any diet. Thank you for the fantastic recipe!

Yay!! I’m so glad you enjoyed the recipe! It’s one of my personal favorites:-) Good luck on your whole30 journey. I’m going start another round but probably not until January 2018. I have tons of whole30 slow cooker recipes on my site. Just search under the category.

OMG my mistake. I thought you were asking about my 5-Ingredient SHRIMP Fajita soup recipe that I just posted. There’s no broth in this steak fajitas recipe, just the salsa. If I just ruined your dish with my own miscommunication please email me at: fitslowcookerqueen@gmail.com and we’ll work something out. Totally my fault for misreading.

All I can say is omg!! These were SO good, I made these for the guys in my house and had planned on eating something else because I don’t like steak…..well, I ate 3 fajitas to myself, they were delicious!! Thank you for the recipe.

Made this with chicken. YUM! Everyone,the one year old to the grandparents loved it. I browned and precooked the chicken about 20 minutes because I needed to hurry things along. Then I dumped all the ingredients into the crock pot leaving the juice that cooked out of the chicken behind. I loved the fajita flavoring mix and will be using it often in all my Tex Mex dishes.

THAnK YOU so much for the positive feedback. I recently updated the recipe to include chicken after reading your comment. I use the seasoning all the time too – taco, fajitas, heck even on veggies haha!

This sounds delish and perfect for not heating the house up on a warm summer evening. Although I will be making it with the beef, I was wondering if replacing with the same amount of chicken changes the cooking time?

It is currently cooking right now (have about 4 more hours for it to be on low for 8 hours) but the meat is so flavorful! How do you think I should turn the delicious juices into a sauce to top off the fajitas? I would like it to be a little thicker. Thank you!! 🙂

I fixed this tonight but it didn’t turn out like fajitas instead it was more like Carne Guisada, which my guys like but I wanted fajitas. I did everything like you did except I used a 14 oz can diced tomatoes instead of the salsa and I used 2 lbs of thin sliced beef tenderizer (pkg said Maltese ). I cooked on low for 7 hours. I don’t know what happened. I asked husband if he wanted me to keep it or throw it out. He said keep it he liked it. He put it over Spanish rice with cheese. I told him well I guess I know how to make Carne Guisada. Lol
Don’t get me wrong it had a good taste but had my taste buds ready for fajitas.
Still looking for a good fajita recipe.

Yikes. While carne guisada is good, I understand it’s not what you were looking for. Did it by chance it on warm? Even if not, since every slow cooker heats differently, you’re just might heat on the high side. I’m asking because this has actually happened to me and it was a result of me accidentally overcooking it. Even if you followed the setting exactly. If you chose to make the recipe again (I hope you do), I would suggest reducing the cook time. I’m sorry the recipe did not work out for you. xShannon

I tried this we loved it I used 2 peppers eachred green yellow and 3 onions 2 yellow and 1 red we just like a lot of peppers and onions thank you so much Fit Slow Cooker queen keep the recipes coming I love to cook and I like trying different things

I doubled this recipe and we ate off of it for a LONG time. We made fajitas one night, my husband ate it another night with a side of mashed potatoes and asparagus, another night he ate it over rice. I took it to work several days and made fajita steak salad, with spinach and avocados. DELISH ! thanks for this recipe.

Just have all but the chili powder in my slow cooker at 11:50 pm. Will leave it on low until morning…and check it then. Need to add the chili in the morning as we need to go get some! Thought I had but hubby has searched and searched and can’t find it. So will update this once we have it finished tomorrow and give it a taste. Love the fact it is only 5 ingredients (well the fajita spices need to be done ahead to add and I am afraid we will be adding the extra tbsp of the chili powder so it is a tad more than you call for but I BET it is forgiving this recipe) and in a slow cooker so I only had to do the slicing and the mixing – the pot does the rest! Yup, my kind of recipe and I have pinned it. If we like it I will be giving it my YEAH! on my Pinterest page where I have the recipes I have tried and YEAH and NAY them! 🙂

Well! It was ABSOLUTELY a rave! The guys in the family liked it SOOOOO much that they ASKED if we could have the leftovers for the next day supper meal! I loved it also. It was easy to make. I LOVE that it only uses 5 ingredients. I found that it needed to be allowed to “cook down” in order to remove some of the moisture. That might have been because I used two LARGE peppers, a LARGE onion, and because I did not measure exactly the amount of salsa and I used a combo of two of them. One was a homemade one I obtained from our local online market, and because it was not quite as much as indicated I added a Tostitos medium salsa to top it up. As well, I used stew beef that I cut into short, short strips. Not sure why but the end result had a LOT of liquid in it. Maybe I needed more meat since I think I was short the 2 lbs by a wee bit. But anyway, we used a slotted serving utensil to take the mix out of the dish I had put it in and that worked mostly. The main point is that I used your Fajita spice mix and it worked perfectly. The mix given was JUST enough for this pot of slow cooker fajita. So I know I can make this ahead and bottle it for us as it is great! Very very tasty. At any rate, if there was a star rating of 5 I would be giving this recipe a 5+ cause it is just too awesome to pass up! Yup we WILL be doing this again. And oh yes, making this motivated me to also make our own guacamole which my brother insisted I need to have available ALL the time in future and refried black beans to add to our supper. Both the guacamole and the refried beans were found on Pinterest and both were a big hit with my husband and I, although the beans seemed as if they were avoided by my brother. Hmmm… but I liked both of those too. When two guys rave about something you KNOW it has to be good! Yup! THANK YOU!

I would sautee the veggies until they were soft before adding them to the slow cooker. Then add the rest of the ingredients, stir, and cook on HIGH for 30 min or so or LOW about a hour. This is just my best educated guess, I haven’t actually tried this:-) Let me know how it turns out! xShannon

Thank you for sharing!! My husband recently had to get all his teeth out and we cannot yet afford dentures that fit properly and he has always been a big meat eater so I feel blessed to find your easy meal ideas. Thanks again ????❤

I’m making this tonight!! My hubby loves all things steak & anything eaten in a taco shell.????
I make my own fajita seasoning also. Store package sodium content is extremely high. I’ll post a comment later on how it turned out. Thanks!

I made this a few days ago and it was wonderful! I had lots of juices left over so I decided to make soup out of the leftovers! I cut up the meat and peppers that were left, added some beef stock, cooked brown rice and some corn. Topped it with some sour cream and shredded cheese. It was divine! Thanks for a great recipe!

I’m glad to hear you enjoyed the recipe! The calorie content will depend on the salsa you use and how you serve this (tortilla, over rice, etc) but in general, this a low calorie with approximately 350 calories per serving.

I’ve made this twice already and it is so easy and so delicious. You can make it a little different every time by switching out different types of salsa or tomatoes [like jalapenos, chipotle, green chilies, etc.] This is going into my favorites folder. Also, highly recommended for mommies with little ones because it takes no time to prepare. THANKS a million for posting! 🙂

You’re very welcome! I’m so glad to hear you enjoy the recipe. I LOVE your ideas…I think I’ll add in jalapenos next time:-) Thank you so much for sharing. I hope you try some more recipes from my blog.

salutations friend i was having a serious debate with my father in law’s 3rd wife and we were wondering how to properly pronounce fajita. she claims that the 2nd a is silent but my english teacher says that the hard J sound makes the F sound like a PH. thanks so much!

Hi! I want to try this recipe next week (it looks delicious) but I need help about the salsa. Which one it is? In my country we have salsa de tomate (ketchup), salsa inglesa (worcestershire),salsa china (soy) salsa verde o de tomatillo (I have not idea how to translate it), barbacoa (BBQ), …. so, could you help me clarifying the ingredient? Thank you.
